jsf default required field validation message seems funny?

[sirpelidor]

hi, i have a following tags in my jsf page wrapped in a <h:form> tag:


<h:outputText value="#{msg.username}" />
<h:inputText id="txt_username" value="#{loginBean.username}" required="#{true}"/>
<h:outputText value="#{msg.password}" />
<h:inputSecret id="txt_pwd" value="#{loginBean.password}" required="#{true}" />
<h:commandButton id="cmd_login" value="#{msg.login}" action="#{loginBean.action}"></h:commandButton>
<h:messages layout="list"></h:messages>


when i purposely -not- to enter any value and hit the login button, i get the following error message on my page:


j_id_jsp_1302903026_1:txt_username: Validation Error: Value is required.
j_id_jsp_1302903026_1:txt_pwd: Validation Error: Value is required.



where's that extract "j_id_jsp_1302903026_1" come from and how to take it away from the page?

thank you

those are the real id's of the components that are generated. you'll see them in the rendered HTML file.

how are you doing the validations?

hi chazzy,

i'm very new to jsf (and jsp) and i haven't done any validation yet. i thought by setting require=true will auto validate the field for me (coming from .net background perspective).

do i have to write my own validation for required field?

thanks!

ok, then let's back up a bit. which jsf implementation are you using?

[sirpelidor]

hum... i don't believe i'm using any implementation at the moment

(the truth is, i don't even know which implementation to choose from, the number of web frameworks and implementations available in java cause quite a bit of confusion for beginner).

all i have right now is jsf-impl.jar and jsf-api.jar from mojarra-1.2.12.

I also have jsf-facelets.jar and el-api.jar in my classpath, but i doubt its doing anything since I can't see any additional tags from eclipse.

this sure is a learning curve for me, but i've been picking up new knowledge everyday :)

[chazzy]

ah

basically, those are the rendered id fields. different implementations work different (e.g. richfaces/icefaces have nonstandard control over it, but then you end up working w/ that jsf implementation only).

i think this might help you figure out how to replace those messages.

(for the record, you get the j_id_jsp_1302903026_1 because you're using jsp's and you're using global messages. if you used local messages for each component, you'll only get the txt_name part).

that link does the trick, thank you chazzy :)
